A bacteriostatic is a compound which has the effect of preventing bacterial growth. These agents do not kill bacteria like bactericidal compounds; instead, they limit further replication of bacteria at the site where they are introduced. Several antibiotic drugs are bacteriostatic agents, with tetracyclines being a notable example.
It does not include anything to prevent bacteria, so once it is penetrated it needs to be used entirely or disposed of. Bacteriostatic water is simply sterile water, with benzyl alcohol added to prevent bacteria growth in the water. Bacteriostatic water can be used for multiple injections spread over up to 30 days. Without the benzyl alcohol the water would not be safe for multi injection use.
